Crane Overhaul
As a marine and offshore cranes supplier, we want to provide our customers with optimal
service for their marine and offshore cranes. In addition to small and medium repairs
executed on-board and in our workshop, we also offer complete overhauls at our specially
equipped workshop in the Netherlands. Often, the existing crane is indispensable, and the
continuity of your workboat/vessel is crucial. We understand that. In most cases, we can
offer you a replacement rental crane for the required overhaul period to guarantee your
continuity. We have made it our business. See our separate brochure for rental options.
Our definition of a complete overhaul is that the
crane will be completely disassembled; all shaft
bores will be machined back to the original
tolerances and fitted with new bronze bushings
and pins—no exceptions.
Which components will be overhauled?
• Slewing rings
• Slewing gearboxes
• Control valve blocks
• Hydraulic cylinders
• Hoisting winches
• Hydraulic and electric rotators
• Radio remote control systems
• Hydraulic hose reel
• Electrical safety systems
Which components will be renewed?
• Pins
• Bushes
• Hydraulic hoses
• Sliding pads
• Electric cable reel
Benefits
• Possibility to upgrade to actual standards
• Possibility to add options
• Reduction of downtime
• New warranty period
• Extended product lifetime
• Customised colour

Our mission:
“Your reliable
partner for
marine and
offshore lifting
appliances”
For an overhaul, we remove the crane from the ship and transport it to our
workshop. Once at the workshop, each component is thoroughly checked
and repaired or replaced if necessary. The final step is a new coating. After
assembly, the crane undergoes an in-house function test to ensure that it
performs according to the Heila standard. If required, we can also carry
out the overhaul of ATEX-cranes. Upon completion of the overhaul, you
receive a technical measurement report.
Extensive operation and exposure to elements like salt water, wind and UV
leave their mark on the crane’s structure. Our cranes are structurally
designed to last at least 15-20 years. Depending on the maintenance level
one or two overhauls may be required throughout that life cycle. Heila is
your one-stop-shop for after-sales support!
For each customer and every vessel, safety, quality and attention to details are
paramount when overhauling cranes. We pay extra attention to the quality of
welds and coating and the finishing of hydraulic pipes and other visible parts.
The type and colour of the coating are selected to match the vessel design.

Before the make-over
Inspection of the crane
Before starting the project, we do a thorough inspection of the crane and and discuss the
possibilities with the customer. When the details are agreed and the plan is set, we transport the
crane to our workshop.
The measurement reports are submitted to the customer. If there are any new findings after
dismantling the crane, we liaise with the customer to determine the plan of action.

The work is almost complete. Our service engineer performs the function tests.
The crane is ready for transport. The last step is the installation and commissioning
on board (HAT) …. job done!
A complete overhaul project takes around 8–10 weeks. The result is a crane that is
as good as new.
